About the GNX2
The Presets
A preset is a named and numbered location of a programmed sound that resides in the GNX2. Presets
can be recalled with the FOOTSWITCHES or the DATA WHEEL. The GNX2 comes with 64
Factory and 64 User presets. The Factory Presets do not let you store changes to them. The User
presets let you store changes. From the factory, the 64 User presets are exact duplicates of the 64
Factory presets. This lets you make your own presets without worrying about losing any of the original
presets. When you select a preset, the name of the preset appears in the green alpha-numeric display and
the number of the preset appears in the red numeric display. The User LED to the right of the numeric
display lights indicating the User preset is active. The Factory LED lights indicating a Factory preset is
active.

Editing Functions
Editing Functions
Editing/Creating a Preset
The GNX2 was designed to make the process of sound creation easy and intuitive. Because the GNX2 provides both Amp Modeling and Effects Processing, the editing functions have been divided into two sections:
the Amp/Cabinet Modeling section and the Effects section. The GeNetX™ technology contained in the
GNX2 allows you to go much further than mere Amp Modeling. GeNetX™ lets you create your own
Amp/Cabinet HyperModel™ and store this custom creation to a User Amp/Cabinet location. When editing
either the Amp/Cabinet Modeling, or the Effects section, you must start with one of the User or Factory
Presets. It is not possible to start with a completely empty preset. The preset you begin with does not need
to be in the location that you intend to save it. To begin creating a HyperModel™ or just edit the effects, you
must select a preset as your starting point.
Amp/Cabinet Modeling
Once you have selected a preset, you can select the Amp Models or Cabinet Types for your preset.
Amp/Cabinet Modeling is a technology that applies the tone of one of several vintage or modern Amp
Models and Cabinet Types to your guitar signal. The GNX2 includes accurate emulations of 15 popular Amp
Models, 1 Acoustic Guitar Simulation, and 12 Speaker Cabinet Types.Your choices include:

Editing Amp Models and Cabinet Types
Each GNX2 preset has a Green, Red, and Yellow (Warped) Amp Channel. The Green and Red Amp
Channels include individually selectable Amp Models, Cabinet Types, Gain, EQ, and Level settings.The
Speaker Cabinet can also be tuned meaning that you can select the Cabinet’s resonant frequency. Once
the Models have been selected for the Green and Red channels, the channels can be toggled instantly
using the Amp Channel Footswitch (only when FX Mode is active).Then the characteristics of the
two Models selected for the Green and Red channels can be Warped together resulting in a completely
new HyperModel™.

Effects and Parameters
Effects and Parameters
The GNX2 can be thought of as several different “virtual” amplifiers, and individual, hi-tech stomp boxes.
With stomp boxes, the order in which they are connected can make a big difference in how good the overall
sound is. Whether the stomp boxes are placed before the amp, or in the amp’s effects loop will also make a
difference. The GNX2 has the effects connected in the most logical, and best sounding order. The following
diagram shows the signal path through the processing contained in the GNX2.
Effect Definitions
Each Effect within the GNX2 is fully programmable to suit your personal tastes and application.
Understanding how these effects alter the sound, and how each parameter alters the effect will help you
achieve the sound you are looking for. The following overview outlines how each effect and parameter in the
GNX2 will alter the sound.
Wah-Pickup
AWah is an effect controlled by the Expression Pedal. A Wah applies a boost in gain to a narrow band of
frequencies. As the Expression Pedal is rocked back and forth, the center frequency receiving the boost is
swept up and down making the guitar sound as if it is saying “Wah.” The Wah is engaged and disengaged
by applying pressure to the V-Switch located under the toe of the Expression Pedal. See page 40 for
more information regarding the V-Switch.
The Pickup Simulator applies the warmth and thickness of a double coil humbucker pickup to a single coil
guitar, or the unique, crisp sound of a single coil pickup to a guitar with a humbucker.This allows you to
have the best of both worlds without ever changing guitars.
Wah On/Off - The Status button (or the V-Switch) turns the Wah (Wah) on and off.
Wah Type - The Number 1 knob selects the type of Wah.Values include: Cry Wah (CRY) is a traditional
sounding Wah, Boutique Wah (BOuTIQUe) is a wide sweeping Wah with a more modern
sound and Full Range Wah (FULlRaNG)sweeps the entire spectrum of audible frequencies.
Wah Minimum - The Number 2 knob is used to select the minimum point the Wah (WAH MIN) will
reach in the toe up position of the Expression Pedal. Ranges from 0 to 99.
Wah Maximum - The Number 3 knob is used to select the maximum point the Wah (WAH MAX) will
reach in the toe down position of the Expression Pedal. Ranges from 0 to 99.
Pickup Type/Off -The Number 4 knob selects the type of Pick Up to be be simulated.Values include:
Pickup Simulator Off (PiCKOFF), Single Coil>Humbucker (SC>HumB) gives a single coil
pick up the warm tone of a humbucker , and Humbucker>Single Coil (HumB>SC) gives
a humbucker the unique sound of a single coil .
The Number 5 knob doesn’t function when the Wah-Pickup module is selected.
Compressor
A compressor is used to increase sustain, and tighten up guitars. A compressor sets boundaries for a
signal’s strength. When a signal exceeds the set boundary, it is forced back into the set boundary. As the
signal fades to a point where it no longer exceeds the boundary, the compressor expands the signal
strength and increases sustain. The compression parameters are as follows:
Comp On/Off - The Status button turns the Compressor (Compress) on and off.
Attack - The Number 1 knob adjusts the length of time it takes for the Compressor to respond to a
signal exceeding the Threshold. Values include: fast, meDIUM, and slOw.
Ratio - The Number 2 knob adjusts the input to output ratio once the Threshold has been exceeded.
18
Effects and Parameters
For instance, a Ratio of 4 to 1 means that a signal exceeding the Threshold by 4 dB will only be
allowed 1 dB of increased output. Higher settings yield a tighter, sound and increase sustain.
Lower settings allow better dynamics. Ranges include: ¡2-1 (1.2:1), ¡5-1 (1.5:1), ¡8-1 (1.8:1),
™0-1 (2:1), ™5-1 (2.5:1), £0-1 (3:1), ¢0-1 (4:1), ∞0-1 (5:1), •0-1 (8:1), 10-1 (10:1), 20-1 (20:1),
and INF-1 (infinity:1).
Threshold - The Number 3 knob selects the Threshold (threshld). The Threshold is the level a signal
is allowed to reach before the compressor begins to work. Low Threshold settings activate
the compressor with weaker signals. Higher settings require a stronger signal to activate
compression. Ranges from 0 to 99.
Gain - The Number 4 knob adjusts the Output Gain (Gain) from the Compressor. This parameter is
used to balance the level of the Compressor to reach unity gain. Other effects can clip if the
Compressor Gain too high. Ranges from 0 to 20 (dB).
The Number 5 knob doesn’t function when the Compressor is selected.
Whammy/IPS
This module includes 4 types of pitch altering effects:Whammy™, IPS, Detune, and Pitch Shift. The Status
button turns the Whammy/IPS (Wham/IPS) module on and off. The Number 1 knob (Type) selects
whether the module is a Whammy™(WHAMMY), Intelligent Pitch Shifter (IPS), Detuner (DETUNE), or
Pitch Shifter (PITCH). Parameters 1, 2, and 3 in the Matrix have different functions depending upon which
effect is selected in this module.
Whammy™ is an effect that uses an Expression Pedal to bend the pitch of the incoming signal, or add a
bendable harmony with the original signal. As the Pedal is moved, the note bends either up or down.
When Whammy™ is selected, it is automatically placed before the Amp Modeling as shown in the block
diagram (see page 49).The Whammy™ effect must be linked to the Expression Pedal in order to function.
See page 37 for more information on linking the Expression Pedal.
Parameter 1 (Whammy™) - The Number 2 knob selects the interval and direction of the pitch bend.
Choices are as follows:
Whammy (no Dry Signal)

Parameter 2 (Whammy™) - The Number 3 knob provides a manual control of the Whammy™ pedal
position. Ranges from 0 to 99.
The Number 4 knob has no function when the Whammy™ is selected.
Intelligent Pitch Shifting (IPS)
Intelligent Pitch Shifting makes a copy of the incoming signal, and then changes the pitch of the copied
note to a diatonically correct interval specified by the Amount parameter. An Intelligent Pitch Shifter
sharpens or flattens the shifted pitch in order to keep the specified interval within the selected key and
scale creating a true harmony.
Parameter 1 (IPS) - The Number 2 knob selects the Amount or harmony interval for the Intelligent

Gate.The Gate Threshold (THRESHld) parameter ranges from 0 (opens easily) to
40 (requires strong signals to open).
Gate Attack - The Number 3 knob adjusts the length of time it takes the gate to open (ATTACK) and
the signal to become audible once the Threshold has been exceeded. Ranges from 0
(immediate signal), to 9 (This setting will gradually ramp up the volume).
*Pluck Sensitivity - Selects the threshold (PLUCK) where the Gate retriggers when using the Pluck
type Noise Gate.This parameter is only available when Pluck is the selected type
of Noise Gate. Ranges from 0 (requires strong signals to retrigger) to 99
(retriggers with weak signals).
The Number 5 knob does not function when the Noise Gate is selected.
Talker™
The Talker™ is an effect designed exclusively by DigiTech, that lets your instrument speak. The Talker™
requires a microphone be connected to the Mic Input on the rear panel of the GNX2. As you speak into
the microphone, your instrument mimics what you say. The Talker™ effect is output only at the 1/4” left
and right outputs. When the Talker™ is bypassed, the mic signal is passed from the XLR mic in to the
XLR mic out unaffected. There are five types of Talker™ selections to choose from.
* These Parameters are only available using the GENEDIT™ computer editor software.
Type - The Number 4 knob is used to select the 5 Talker™ types and turns the Talker off (talkoff).
Talker types range from talker 1 (deep tonal characteristics), to talker 5 (bright tonal
characteristics).
Sensitivity - The Number 5 knob is used to adjust the microphone sensitivity for the Talker™ effect.
The Talker™ must have an appropriate input level from your microphone in order to work
properly. If the microphone input is too weak, the Talker™ will have trouble tracking. If the
input is too strong, the Talker™ will clip making the words unintelligible.The Mic Sensitivity
ranges from 1 being the least sensitive to 99 being the most sensitive.
Chorus/Mod Effects
The Modulation Effects group is a multi-function module allowing you to select effects such as; Chorus,
Flanger, Phaser,Triggered Flanger,Triggered Phaser,Tremolo, Panner,Vibrato, Rotary Speaker, AutoYa™,

to 99.
The Number 4 knob does not function when the Pitch Shifter is selected.
DELAY
Delay records a portion of the incoming signal, and plays it back a short time later. The recorded segment can repeat just once, several times, or infinitely (that turns off the input to the Delay and lets
you play over the top of a passage in the Delay loop). The Delay in the GNX2 also includes a Ducker
Threshold that lets you set the signal strength required before the Delay records. This feature lets
you control the Delay with your playing.
Delay On/Off - The Status button turns the Delay (delay) on and off.
Delay Type - The Number 1 knob selects one of the 5 different types of Delay. The Delay choices
include:
MONO (clear concise repeats)

Tutorial
Suppose you wanted to create your own HyperModel™ that incorporated the sweet tones of a vintage
Tweed using an American 2x12 cabinet, and the ripping distortion of a Rectified Amp with a British 4x12 cabinet. Let’s also suppose that we want to be able to toggle between an acoustic guitar simulation and this new
HyperModel™ with a preset that gives your single coil pickup a humbucker sound, uses no Compression, has
a Noise Gate that opens quickly, a subtle Chorus effect, no Delay, and a little bit of a Hall reverb.The following steps guide you through the process for creating just such a preset in the GNX2.
Select a Preset
The first step to create a preset is to select your starting point.You can start with any preset, but for this
example let’s start with Preset 40. Use the Footswitches or the Data Wheel to select Preset 40.
Create a HyperModel™
For this example, we are going to use a vintage Tweed amp with an American 2x12 Cabinet, and warp it with
a Recitified Amp using a British 4x12 cabinet. Select Preset 40, and the GNX2 is ready to select the Amp
Models (indicated by the Status button’s yellow LED).
Select the Green Channel Amp and Cabinet
The LEDs next to the Number 1 and Number 2 knobs are green indicating they will select the Amp and
Cabinet types for the Green Channel. To assign the vintage Tweed amp to the Green Channel, rotate the
Number 1 knob until the display reads TWEED (Tweed). Then rotate the Number 2 knob until the display
reads AMer2X12 (American 2x12).
Select the Red Channel Amp and Cabinet
The LEDs next to the Number 4 and Number 5 knobs are red indicating they will select the Amp and
Cabinet types for the Red Channel.To assign the Rectified amp to the Red Channel, rotate the Number 4
knob until the display reads rectfied (Rectified).Then rotate the Number 5 knob until the display reads
BRit4X12 (British 4x12).
29
Tutorial
Adjust the Green Channel Parameters
The Tweed amp that we selected for our Green Channel assignment uses the factory default settings for
the Gain, EQ, and Level Parameters.Therefore, you may want to change the settings. To access the Green
Channel Parameters, press the STATUS button. All horizontal LEDs light green indicating that all 5
knobs will adjust the Green Channel Parameters. Rotate the Number 1 knob to adjust the Tweed Gain.
Rotate the Number 2 knob to adjust the Tweed Bass. Rotate the Number 3 knob to adjust the Tweed
Mids. Rotate the Number 4 knob to adjust the Tweed Treble. Rotate the Number 5 knob to adjust the
Tweed Level.
Adjust the Red Channel Parameters
Like the Tweed amp in the Green Channel, the Rectified amp in the Red Channel may need to be adjusted
to suit your personal taste. To access the Red Channel Parameters, press the STATUS button. All horizontal LEDs light red indicating that all 5 knobs will adjust the Red Channel Parameters. Rotate the
Number 1 knob to adjust the Rectified Gain. Rotate the Number 2 knob to adjust the Rectified Bass.
Rotate the Number 3 knob to adjust the Rectified Mids. Rotate the Number 4 knob to adjust the
Rectified Treble. Rotate the Number 5 knob to adjust the Rectified Level.
30
Tutorial
Tune the Cabinets (optional)
You may also want to adjust the resonance for the American 2x12 and the British 4x12 Cabinets. To
access the Cabinet tuning for both Red and Green Channels, press and hold the STATUS button until
the display reads CAB TUNe (Cabinet Tuning). Release the Status button and rotate the Number 2 knob
to adjust the tuning for the Green Cabinet (gtune º0) and the Number 5 knob to adjust the tuning for
the Red Cabinet (rtune º0). Once the tuning of both Cabinets has been adjusted, press the STATUS
button to return to Performance mode.
Warp the Green and Red Channels Together
When the Amps and Cabinets in our Green and Red Channels are dialed in to suit our taste, we can
Warp their characteristics together to create a new HyperModel™. Make sure your GNX2 is in yellow
mode (indicated by the yellow lit Status LED). If it is not in yellow mode, press the Status button until the
Status LED turns yellow. Then rotate the Number 3 (Warp) knob to blend the Amps and Cabinets in our
Green and Red Channels.
Save the HyperModel™
Now that we have designed our own Amp/Cabinet HyperModel™, we need to save it to one of the 9
User HyperModel™ locations. This allows us to use it in presets. Press the AMP SAVE button until
the display reads NEW AMP and the first letter (N) is flashing. For this example, let’s name the
HyperModel™ “Rectweed” (Rectified Tweed). Rotate the DATA WHEEL to select R as the first letter.
Then press the RHYTHM button to select the next character in the display. Continue using the Data
Wheel and Rhythm button until the display reads RECTWeeD.
When the display reads RECTWeeD, press the AMP SAVE button again. Now we need to choose one of
the 9 User HyperModel™ locations.The alpha-numeric display should read EMPTY (Empty) and the red
numeric display should read U1 if this is the first HyperModel™ stored to your GNX2. Press the AMP
SAVE button again to save to this Amp location.The display briefly reads AMP SaVD (Amp Saved) and
then returns to the name of the selected preset.

Tutorial
Select Models for the Preset’s Channels
In the previous steps, we selected a Tweed for the Green Channel and a Rectified Model for the Red
Channel.Then we Warped the two together to create our HyperModel™.This HyperModel™ is saved as
an amp type that we named Rectweed, but it is not currently part of our preset. In this example preset,
we need to be able to toggle between an acoustic guitar simulation and our new HyperModel™.To do
this we need to select the Acoustic model for the Green Channel and Rectweed for the Red Channel of
our preset.The LED next to the Status button should be yellow. If it is not, press EXIT. Now rotate the
Number 1 knob until the display reads ACOUSTic.This is the Green Channel Model for the preset.
Rotate the Number 4 knob until the display reads RECTWeeD (our new HyperModel™).This is the Red
Channel Model for the preset. This lets us toggle between these two sounds using the Amp Footswitch
(when FX Mode is active).
Edit the Preset
The next step to creating our example preset requires entering the Effect Edit mode.To do this, press
the EFFECT SELECT DOWN button. The Matrix LED in the Wah-Pickup row lights. The display
briefly reads EDIT and then cycles between the status of the Wah and Pickup Simulator effects. If the
red display reads on WAH On, press the STATUS button once to turn it off (since our example is not
using a Wah).
Select the Pickup Type
In our example preset we are using a single coil pickup, but want it to sound like a double coil humbucker. With the Wah-Pickup LED lit, rotate the Number 4 knob until the display reads SC>Humb.
This makes a single coil sound like a Humbucker.

Tutorial
Turn the Compressor Off
We don’t want to use compression in our preset so, we need to turn the compressor off. Press the
EFFECT SELECT DOWN button. The Compression LED lights and the display shows the current
status of the Compressor. If the Compressor is on, press the STATUS button until the red display
reads off (Of).
Turn the Whammy™/IPS Off
We don’t want any Whammy™ or IPS effects in this preset. Press the EFFECT SELECT DOWN
button, and the Whammy/IPS LED is lit. If the display indicates that either one of these effects is
active, press the STATUS button until the Display reads off (Of).
Turn the Stompbox Modeling Off
We don’t want any Stompbox Modeling in this preset. Press the EFFECT SELECT DOWN button, and the Stompbox LED is lit. If the display indicates that it is active, press the STATUS button
until the Display reads off (Of).
Adjust the EQ
The EQ for both the Acoustic Model (Green Channel) and the Rectweed HyperModel™ ( Red
Channel) can be adjusted individually. To adjust the EQ, press the EFFECT SELECT DOWN button, and the Equalizer LED lights. The GNX2 defaults to the Green Channel EQ adjustments.
Therefore, the display briefly reads EQ green . Rotate the Number 1 knob to adjust the Red
Channels Bass enhancement. Rotate the Number 2 knob to select the center frequency for the Midrange. Rotate the Number 3 knob to adjust the Mid-range enhancement. Rotate the Number 4 knob
to select the center frequency for the Treble. Rotate the Number 5 knob to adjust the Treble
enhancement. Press the AMP Footswitch to select the Red Channel’s EQ adjustments.The display
briefly reads EQ red and the same knobs adjust the same EQ Parameters for the Green Channel.
33
Tutorial
Adjust the Noise Gate
For our example, we want our Noise Gate to open quickly with a relatively weak signal.This type of
gate uses the Silencer™ with a low Threshold and short Attack Time. Press the AMP
FOOTSWITCH to select the Red Amp Channel. Press the EFFECT SELECT DOWN button
and the Noise Gate’s LED lights. If the display reads off (Of), press the STATUS button until the display reads on (On). Rotate the Number 1 knob until the display reads SILeNCeR for the type of
gate. Rotate the Number 2 knob to set the Threshold to 20 (this may need to be adjustment depending upon your guitar). Rotate the Number 3 knob to set the Attack Time to 0 (fast attack).
Turn the Talker™ Off
In our example preset we don’t want the Talker™ effect to be used. With the Gate - Talker LED lit,
rotate the Number 4 knob until the display reads talk off. This will turn off the Talker™.
Select and Adjust the Chorus
Next we wanted to thicken up the sound in our preset by adding a subtle Chorus effect. Press the
EFFECT SELECT DOWN button again and the LED in the Chorus/Mod row lights. If the display
reads off (Of), press the STATUS button until the Display reads on (On). Then rotate the Number 1
knob until the display reads Chorus (Chorus) for the effect type. Rotate the Number 2 knob to set
the Chorus Speed to 5. Rotate the Number 3 knob to set the Chorus Depth to 30. Rotate the
Number 5 knob to set the Chorus Level to 50.
34
Tutorial
Turn the Delay Off
In our example preset we want to bypass the Delay. Press the EFFECT SELECT DOWN button
again and the LED in the Delay row will light. If the display reads on (On), press the STATUS button
until the display reads off (Of).
Select and Adjust the Reverb
In our example preset we wanted a little bit of Hall Reverb to provide some ambience. Press the
EFFECT SELECT DOWN button again and the LED in the Reverb row lights. If the display reads
off (Of), press the STATUS button until the display reads on (On). Rotate the Number 1 knob to
select Hall (Hall) for the Reverb Type. Rotate the Number 2 knob to set the Reverb Predelay to 2.
Rotate the Number 3 knob to set the Reverb Decay to 15. Rotate the Number 4 knob to set the
Reverb Damping to 40. Rotate the Number 5 knob to set the Reverb Level to 30.
Store the Preset
The last step, is to store our changes to a User Preset. If we changed presets or turned the GNX2
off without storing these settings, it would forget what we had done and revert back to the original
preset.To store the preset, press STORE. The first letter in the Display begins to flash. Since this is
an example preset, let’s name the preset examplE. Rotate the DATA WHEEL until the flashing
character in the display is an E. Press the RHYTHM button once and the second character begins
to flash. Use the Data Wheel again until the flashing character is an X. Continue using the Rhythm
button to select the character location and the Data Wheel to change the characters.
35
Tutorial
Once the Display reads exampLE, press STORE again.The numbers in the red numeric display are
flashing. Using the Data Wheel, select 64 as the destination. Press STORE once more to save the
preset.
Congratulations! You have successfully created a Preset.

Expression Pedal
The Expression Pedal on the GNX2 can control up to 3 parameters in real time including the Volume,
Whammy™, and Ya Ya™. When a parameter has been assigned to the Expression Pedal, the parameter’s minimum and maximum values can also be programmed.The GNX2’s Expression Pedal includes DigiTech’s exclusive V-Switch.The V-Switch allows you to switch the Expression Pedal assignment on the fly. Applying extra
pressure to the toe of the Expression Pedal engages the V-Switch and the Expression Pedal switches between
the assigned parameter and Wah. The sensitivity or amount of pressure required to engage the V-Switch can
be adjusted to suit your personal taste (or weight of your foot). See page 40 for the V-Switch Sensitivity
adjustment procedure.
The procedure for assigning a parameter to the Expression Pedal is as follows:
1. Press the EFFECT SELECT button until the Exp Assign row has been selected.
2. Press the STATUS button until the display reads exp pdl1 (Expression Pedal Link 1), exp pdl2
(Expression Pedal Link 2), or exp pdl3 (Expression Pedal Link 3), depending upon which assignment you
want to use or the number of parameters you intend to assign.The display will alternate between the
Expression Pedal selection and the assigned parameter.
3. Rotate the Number 1 knob until the parameter appears in the display. See the Expression Parameter
Assignment List on page 38 for a complete list of assignable Parameters.
4. Rotate the Number 2 knob to select the minimum value the parameter reaches with the Expression Pedal
in the toe up position (not available when volume is the assigned parameter).
5. Rotate the Number 3 knob to select the maximum value the parameter reaches with the Expression Pedal
in the toe down position (not available when volume is the assigned parameter).
6. Store your Expression Pedal assignment to your preset. See page 16 for more information on the storing
procedure.
LFOs
The GNX2 includes two low frequency oscillators (LFO1 and LFO2) that can be assigned to the
Expression Pedal parameters. A low frequency oscillator automatically varies the value of the assigned
parameter at a steady rate. A minimum and maximum value can also be assigned. For instance: if the Amp
Gain was assigned to LFO1, and the minimum value was set at 1 and the maximum value was set at 99,
the GNX2 would automatically sweep the amount of distortion from clean to distorted and back to
clean. Individual LFO speeds can also be assigned. In the previous example, the LFO speed would determine the length of time it took the LFO to sweep from the clean to the distorted sound.The procedure
for assigning the LFOs in the GNX2 is as follows:
1. Press either EFFECT SELECT button until the Exp Assign row is selected.
2. Press the STATUS button to assign LFO1 (LFO 1) or LFO2 (LFO 2).
3. Rotate the Number 1 knob until the Parameter is displayed. See the Expression Parameter Assignment
list on page 38 for a complete list of assignable Parameters.
4. Rotate the Number 2 knob to select the minimum value the assigned parameter reaches at the bottom
turn around point for the LFO (not available when volume is the assigned parameter).
5. Rotate the Number 3 knob to select the maximum value the assigned parameter reaches at the top
turn around point for the LFO (not available when volume is the assigned parameter).
6. Rotate the Number 4 knob to select the speed that the LFO oscillates from the minimum to the maximum values. LFO speed ranges from (.O5 HZ) to 10 Hz (1ºO HZ).
7. Rotate the Number 5 knob to select the waveform the LFO oscillates on.Your choices include:
37
Other Functions
triangle (Triangle) - a smooth rise and fall, but abrupt turn around in oscillation.
SINE (Sine) - a smooth rise, fall, and turn around in oscillation.
SQUARE (Square) - an abrupt rise, fall, and turn around in oscillation.
8. Store your LFO assignment to your preset. See page 16 for more information on the storing procedure.
Amp Footswitch
From the factory, the Amp Footswitch switches between the Green and the Red Amp Channels. However,
the GNX2 allows you to select the Amp Footswitch function.The procedure for assigning the function of
the Amp Footswitch is as follows:
1. Press either EFFECT SELECT button until the Exp Assign row is selected.
2. Press the STATUS button until the display reads AMP FS (Amp Footswitch).
3. Rotate the Number 1 knob to select the Amp Footswitch function.Your choices include:
G-R - Switches between the Green and Red Amp Channels.
G-Y - Switches between the Green and Yellow (Warped) Channels.
R-Y - Switches between the Red and Yellow (Warped) Channels.

Dry Track
This feature is useful for recording dry guitar tracks with the intent of adding processing after the guitar
tracks have been recorded. All effects can be monitored through the analog left/right and headphone outputs when Dry Track is enabled. Dry Track can tap the signal before or after the Mod Effects, Delay, and
Reverb modules, or off the Input. With Dry Track 1 enabled, the signal delivered to the Digital Output
signal includes processing from the Pickup Modeling module through the Noise Gate module. With Dry
Track 2 enabled, the signal is tapped of the input jack and sent directly to the digital output. This lets you
record an unprocessed signal that can be fed back into the input for the purpose of ‘re-amping’ your signal through different amp models. If Dry Track is disabled, the signal is tapped off after all effects (same as
the analog outputs).To access the Dry Track option:
1. Press the UTILITY button. The Utility button’s LED lights indicating you are in the Utility section.
